Abstract: An agricultural cultivator includes a single elongate tubular tool bar of circular cross section which is split into a centre section and two wing sections interconnected with the centre section at outer ends thereof through pivot couplings. The center section of the tool bar is mounted on two ground wheels and the outer end of each wing section is mounted on a respective one of a pair of ground wheels. Each ground wheel is connected to the tool bar by a respective brace. The ground wheels are aligned so that there axes of rotation lie on a common line forwardly of the tool bar. The braces are interconnected with a hitch frame for pivotal movement relative to the hitch frame about pivot pins defining a common pivot axis parallel to the tool bar and located between the tool bar and the common line of the ground wheels so that rotation of the braces causes the tool bar to move forwardly while the ground wheels move rearwardly under the toolbar. The rotation of the tool bar through approximately 90° lifts the cultivator shanks mounted on individual tool frames carried from the tool bar so that the tool frames stand vertically upwardly from the tool bar in a transport position. In the operating position slight movement of the braces adjust the vertical height of the tool bar from the ground for adjusting the depth setting of the cultivator shanks.

Title: Technique for bridging local area networks having non-unique node addresses
Inventor: FISCHER MICHAEL A
IPC: H04L12/28
Filed: 1994-01-27
Granted: 2000-06-20
Abstract: A bridging apparatus provides the capability of transparently and unambiguously communicating LAN packets between two separate LAN segments (30a, 30b) which have nodes (34) with duplicate IDs. A communicator (60a, 60b) connected to each LAN segment includes a controller which aliases the source identification (SID) of the remotely originated or sourced LAN packets with an unused ID which is an alias (AID) before sending the LAN packet with the AID as its SID on the local LAN segment. The reverse occurs in response to locally sourced LAN packets containing the AID as the SID. The ID of the remote node which correlates to the AID is substituted as the SID before the LAN packet is transmitted to the remote LAN segment. By aliasing in this manner LAN packets are communicated by use of the AID between the nodes (34) having the duplicated IDs on the two LAN segments without changing the LAN protocol.

Abstract: A method of providing a helmet shell or like structure, particularly a face mask for ice-hockey goal tenders, with an impact-absorbing padding while adapting the shape of the padding to the individual shape of the wearer's head. According to the method, a padding blank is first cut from a sheet of thermoplastic material of suitable hardness and the blank is heated to a temperature at which it softens so as to become easily shaped. The blank is then placed in the helmet shell and the shell is placed on the head of the intended wearer and pressed down against the head with a force sufficient for the blank to be brought to the shape of the head and of the helmet shell.   This force is maintained until the blank cools to a temperature at which the material retains its shape whereafter the padding is affixed to the helmet shell with the aid of fastening means applied to the helmet shell and/or the padding. The invention also relates to a helmet provided with padding that has been shaped in accordance with this method.

Title: Ion spray with intersecting flow
Inventor: COVEY THOMAS R
IPC: H01J49/04
Filed: 1995-01-09
Granted: 2004-09-21
Abstract: Liquid from a liquid chromato- graph or other sample source, prefer- ably assisted by a high velocity coax- ial gas jet, is sprayed through a cap- illary tube (40') producing a flow in a first direction of charged droplets (50'). A flow of heated gas (60), in a second direction different from the first direction, intersects the droplet flow at a region (64) upstream of an orifice (20'). The flows mix turbu- lently, with the second flow helping to evaporate the droplets to produce ions and helping to move the evapo- rating droplets toward the orifice (20'), providing a focusing effect. Ions are drawn through the orifice (20') into a mass analyzer and analyzed. Alter- natively the flows of liquid and heat- ing gas can be directed toward each other and at right angles to the axis through the orifice, and the inhaling effect of the orifice can be used to draw droplets toward it, or a third gas flow can be used for this purpose. The heated intersecting gas flow typically provides an increase sensitivity (ion counts per second) of between 10 and 100 times. Heating the droplet plume also allows controlled desaturation of ions and an increase in the number of charges on them, without degrading the io ns.

Title: System and method for automated network reconfiguration
Inventor: NUSBAUM KURT
IPC: H04M7/12
Filed: 1997-04-30
Granted: 2000-12-12
Abstract: A method is disclosed for providing an enhanced level of security for sensitive or proprietary information associated with information transactions in a public network, such as the Internet. In carrying out that method, an on-line information transaction is bifurcated between a generalized information access portion of such a transaction and an exchange of sensitive user information.  With such a bifurcation, the generalized information access portion of the transaction, which generally would constitute the more substantial (in terms of network resources) portion of the transaction, would be handled via a non-secure network, usually a public network such as the Internet. The portion of the transaction involving sensitive user information, on the other hand, would be handled by a separate secure connection, such as a private network, or intranetwork. An important characteristic of this bifurcation arrangement is the provision of a means for automated reconfiguration of a user terminal as between accessing the generalized information via the non-secure network and access to the secure communications network for the exchange of sensitive user information. Such an automated reconfiguration will be carried out without the necessity for any action on the part of the user, and indeed will be largely invisible to the user.
